Abstract
A display (10) utilizes a drive scheme that minimizes power dissipation by reducing the operating frequency at which columns (12) operate. The operating frequency is reduced by positioning column timing signals (32) near an end of a horizontal display time (38,39,48,49) if the next horizontal display time also has data to be displayed.
